Item # 44510-1061, SR106ED Safety Expansion Unit




  • Power requirements-the SR106ED will accept 24 VAC/DC, 115 VAC or 230 VAC
  • Outputs-the SR106ED has 3 N/O delayed outputs to route power to the coils of power contactors (delay selectable from 1 to 30 sec.)
  • Auxiliary Output-the SR106ED has 1 N/C auxiliary for monitoring by the safety monitoring relay
  • PLC Compatible-The N/O off delayed output makes it possible to use the SR106ED on machines with Programmable Logic Controllers that require some time to execute an orderly shutdown.
Specifications are subject to change without notice.

Note: The safety contacts of the Omron STI switches are described as normally closed (N/C)-i.e., with the guard closed, actuator in place, and the machine able to be started.
